Product Details

Best choice for single swing driveway gates!

The Mighty Mule MM371W allows you to conveniently control your gate from anywhere using your smartphone app. Simply connect it to the Mighty Mule Smart Control App (requires the MMS100 Wireless Connectivity Kit, sold separately), and you’ll have the power to operate your gate remotely. The MMS100 extends control to gates installed as far as ½ mile from your home.


Gate Compatibility: The MM371W is designed for medium-duty single swing gates. It can handle gates up to a maximum length of 16 feet or a maximum weight of 550 lbs. The approximate opening time at a 90° angle is 14 seconds, depending on the weight of the gate.


DIY-Friendly: Perfect for the Do It Yourself (DIY) property owner, the MM371W comes equipped with detailed instructions and online how-to videos. Additionally, you’ll have access to BILT 3D interactive instructions to assist you throughout the installation process. The gate opener is backed by a 12-month warranty for peace of mind.


Gate Types: The MM371W is suitable for all single gate types, including ornamental, chain link, tube, panel, vinyl, and wood gates.


Solar Capable: If you’re looking for an eco-friendly option, consider adding a Mighty Mule 10-watt solar panel (Model #FM123) to make your gate opener solar-powered.


HomeLink® Compatible: The MM371W is compatible with HomeLink®, allowing seamless integration with your vehicle’s built-in garage door opener system.


UL325 Certified: When it comes to the safety of your home, we don’t compromise. That’s why all Mighty Mule gate operators undergo rigorous testing to meet the highest safety standards set by UL325. Our commitment ensures that you get reliable and secure gate operation for your peace of mind.
